  • slow down the footage without jitter

    Posted by John Suzuki on September 5, 2007 at 9:06 pm

    I have this at work and I’m trying to slow down Cloud stock footage (HD).

    I’m not sure how to use this Twixtor Pro 4.5.

    Could someone point me what I need to do to slow down the speed of footage without jittering?

    thanks

    how much do you want to slow it down, and is it interlaced?

    i don’t have twixtor, but if it is anything like timewarp, you should be able to enter the speed you want it to play at (say 50%) and choose the interpolation method to generate the in between frames (like pixel motion, frame mix…).

    you can do a pretty good job of slowing interlaced footage down 50%, by choosing separate fields (with correct dominance) from the interpret footage setting and setting the frame rate to half the actual frame rate, then putting that in a comp with a standard frame rate.

    if its not interlaced, or you used the deinterlace method described above but want to slow it down further, you can just set the frame rate to a lower rate (using half, or quarter, if it was interlaced, of the actual frame rate can look pretty good in many cases). put that in a standard frame rate comp, set the frame blending to pixel motion and enable frame blending in preview.

    I appreciate it.

    I ended up using the plug-in Twixtor and it looks all right, but I’m not happy with the result.

    I’ll give it a shot with your tips.

    Thanks.
